open.mp Server

What's changed

Major Features

• Introdued fully controllable NPCs as a built-in server feature, removing the need for external NPC plugins and enabling deeper server-side AI and automation.
• Added a C API and C API SDK, allowing developers to integrate open.mp directly with native code and external tooling.
• Added the ability to call Pawn natives from the open.mp C++ SDK, significantly improving interoperability between scripting and native modules.

Networking & Performance

• Significant network performance improvements, resulting in faster synchronization and more responsive gameplay.
• Added multiple sync validation checks to prevent invalid data, spoofed states, and malformed packets.
• MTU values are now validated against the maximum allowed per client version, preventing misconfiguration and instability.

Platform & Compatibility

• Upgraded OpenSSL from 1.1.1 to 3.0.13, officially deprecating legacy Linux distributions and ensuring proper support for modern systems.
• Added environment variable support for config.json, making containerized, CI/CD, and production deployments easier and more flexible.

NPC & Gameplay Improvements

• NPC IDs now allocate from highest to lowest, preventing conflicts and improving predictability.
• Deprecated ConnectNPC in favor of the new built-in NPC system.
• Forced train creation to always use 4 consecutive IDs, fixing long-standing inconsistencies.
• Fixed train passenger synchronization issues.

Stability & Bug Fixes

• Fixed crashes related to gangzones in the checking list during server restarts.
• Fixed random occurrences of player state being set to None after spectating.
• Fixed stdin lock on Linux during server shutdown.
